I had started a new job. Met a very attractive older woman there. We started dating. I found out after a while she also had previously dated one of our other co-workers. No big deal, we all got along fine and it never was an issue. Fast forward about a year. We are in the middle of a fight. We aren’t talking for a few days. I wake up one morning horny as hell. Text her asking her to come over, that I really want to eat her out. She comes over, strips off her clothes, and gets in bed with me. I procede to bury my face between her legs and eat her. She was always a great squirter. So before long, I was a mess. Clean up. Go about our day, etc. Months later she admits something about that morning. Turns out she was with her ex the previous night. He fucked her all night, cumming in her pussy multiple times. She stayed the night there. And in the morning they fucked again. That was when I texted her. She left his house to come to mine. And I ate her pussy with my co-workers cum still inside her. When I asked her about it, she said it was so hot knowing I was eating her with his cum still inside her. Really got her off.
